Primary stability of uncemented standard versus intermediate revision stems in hip arthroplasty: A biomechanical in vitro study

Key Points

• This study aims to compare the primary stability of standard uncemented stems versus intermediate revision stems in hip arthroplasty.
• In-vitro study using an artificial bone model
• Comparison of axial and rotational time-zero stability between STD and REV stems
• Intermediate revision stems exhibited greater axial stability compared to standard stems.
• Rotational stability measurements favored the REV stem design, indicating better fixation.
